Buildings were not needed

[-ahhimane-]

Seriously, the end of the manga didn't live up to the expectations.
Buildings were seriously no needed.
Naruto using a laptop XD
The Gokages could have just made a Video conferencing instead of personally coming to the village.
Kakashi and Gai would have looked better in a swimming pool with babes around serving them. And Kakashi should be the one to come up with this idea to treat Gai.


The Last Page still says that the manga has still something to show us. (not about the movie since there are too many info on it already out on internet)

well without constant strife and hate between the villages ideas and new innovation can spread quickly and develop just as fast so this must development in 10 years is believable also i assume that ninjas now are the army/police for the city and or body guards for royalty and diplomats.However i think small development instead of a massive city already would have been more appropriate but it's the end so what can ya do.

But war is amazing for technology boosts...

They meet in person because that's the tradition and it's more formal.

Also, the buildings were needed because you know, population does increase over time and now all the villages are free to mingle and travel to the others.
